CAR-UNDERFRAMING.

Application led July 12, 1915. Serial No. 39,276.

To n?! lf/1.0m. t may concern.'

Be it known that I, ALvrN B. PATCH, :1 ritizen of the United States`residing at (rlenellyn` in the county of Dnpage. and State of Illinois.have invented a certain new and useful Improvement in Car-Underframing,of which the followingis a full. rlear. concise. and exactdescriptioi-i, reference boina` had to the accompanyinp:r drawings`forming a part of this specification.

This invention relates to improvements in ca r nnderfran'iing.

.\n object of the invention is to provide simple. rhea p. and efiicientmeans for rigidly conIu\ctin l and bracing` men'ibers of acarnndertranie` )mrticnlarly the center sills, hab-sills and body bolster.

vin the drawing forming a part of this sperification. Figure 1 is alongitudinal, veriii-rl. sectional view of a portion of a. carnnderi'rame showin;r my iml'n'ovement in connection therewith. Fig'. 2is a top plan vif: ai of the structure illustrated in Fig. 1, rertainparts beingT broken away to more Clearly illustrate the arrangement. AndFigi'. 3 a vertical, sectional view taken substantially on the line 3 3of Fig. 1.

Tn said drawing, -10 denote wooden center sills, 11 the end sill. 12 thebuil'er block and 13% the subsilisr` the outer ends of -which terminateto the rear of the body bolster 14. Secured to the inner sides of thecenter sills 10-10 are strengthening` and bracing` channels 15 15, thelatter eXtending rearwardly beyond the body bolster, as ciearlyillustrated in Fig, 1. At their forward ends. a tie strap 16 may beemployed extending between the channels 15 15 and also bolted to the endsill 11. Draft sills or plates 17 are riveted to the lower flanges ofthe channel 15-15, said draft members 17 beineY preferably of Z barformation. Iil he draw bar carry-iron is designated by the reference 18.

'lc rigidly connect and brace the various sills and bolster I haveprovided a member A. preferably in the form of a casting. Said member Acomprises a horizontal top web 19 recessed as indicated at 20 to therebylighten it. a depending,r rear vertical wall 21, vertical side flanges22--22 ha ving npstandingr portions "23 overlappingT the outer faces oi'the center sills 1()` horizontal rearwardly extending` flanges 9 4 atthe rear thereof forming pockets for the ends of the sub' Specificationof Letters Patent.

Patented Julie 13, 1916.

sills l and an overhanging' lip or iange 25 at its forward end whichrests upon'a-nd is supported by the top member of the body bolster. rihemember A is secured to the channels 15 by any suitable means such as therivets QG-Qll 'To take up wear or horizontal play, shiins 27 27 may beinserted in the pockets 24 at the ends of the sub-si1ls 13, said shimsheing held in place by any suitable means Such as nails 28`28.

From the preceding description, it will be seen that the castingr A isrigidly supported by means of theI overhang'ingr lip 25 and by being'riveted to the lower fianges of the channels 15--15 the latter being;rsupported by both the center sills to which they are se cured and by thebody bolster'. The center sills 10 being' confined between the channels`15 to which the casting A is riveted, and the opstanding flanges 23-23ot' the castinf: A. are effectively prevent-ed from lateraldisplacement. ln addition to the foregoing' the sub-sills areefficiently supported by the pockets Z4 and longitudinal shocks betweenthe bolster Aand .sab-sills are etliciently transmitted through thecasting A.

Although 'I have herein shown and described what i now .consider thepreferred embodiment. oit' my improvement, yet the same is merelyillustrative and I contemplate all chaages and modifications as comewithin the scope ot the claims appended hereto.

I claim:

1` In car nnderframing the combination with a body bolster. centersills, and subsills. ot' a tying and supporting' member located at therear of the body bolster, said member havingr pockets to receive andhelp support the ends of the sub-sills and an overhanging projectionsupported on top of the body bolster.

Q. ln car under-training, the combination with' a body bolster, centersilis, anged pla-tes secured to the sides of said sills and sub-sills.of a castingat the rear of the bodv bolster having pockets to receiveand help support the ends of said sub-sills and riveted to said flangedplates.

3. in car nnderframing, the combination with a body bolster, centersills, flanged plates secured to the sides of said sills and sub-sills,of a casting at the rear of the body bolster having pockets to receivethe ends of Said sub-sills and riveted to said flanged plates, saidcasting having also a forwardly extended lip overha-nging said bolster.

4. In car underframing, the combination with a bodybols'ter, wood centersills, channels secured to the inner faces of said sills and extendingto the rear of the bolster, and sub-sills, of a supporting and bracinginember, saidemember having shoulders at the rear thereof against whichthe ends of said sub-sills are adapted to abut and provided also with aforwardly extended lip overhanging the body bolster, said member beingriveted to the flanges of said channels.

5. In car underframing, the combination with a body bolster, wood centersills, channels secured to the inner faces of said sills and extendingto the rear of the bolster, and sub-sills, of a supporting and bracinginember, said member having Shoulders at the rear thereof against whichthe ends of said subsills are adapted to abut and provided also with aforwardly extended lip overhanging the body bolster, said member beingriveted to theflanges of said channels, and having also upstandingfianges along its outer edges overlapping the faces of said centersills.

(3. In car underframing, the combination with a body bolster, Woodcenter sills, plates secured to the inner faces of said sills andextending to the rear of thebolster, and sublsills, of a supporting andbracing member having pockets at the'rear end thereof in which the endsof said sub-sills are adapted to be received and supported, said memberbeing also provided' with a forward extension overhanging the bodybolster, said member having also upstanding, longitudinally extendingflanges along its outer edges overlapping the outer faces of said centersills and thereby adarpted to prevent spreading of the latter.

In witness that I claim the foregoing I have hereunto subscribed my namethis 6th day of July, 1915.
